Bosch Rexroth IH15EA-1X/GDB-H500/D/V Part No. R904100778 Clamping and Drive Module Distribution

R904100778 Bosch Rexroth UPE 2 clamping and drive modules constitute a complete drive system that is ready for connection upon delivery. They are used to supply hydraulic oil to the hydraulic circuit. Due to thermal load considerations, the clamping and drive modules operate in short-time and intermittent duty modes. The duty cycle is selected based on power output and ambient conditions so that the maximum permissible operating temperature of 80 °C is not exceeded. The clamping and drive module basically consists of an aluminum housing, a pump (radial piston pump or external gear pump), and an oil-immersed motor. The stator of the oil-immersed motor is pressed into the aluminum housing. It transfers the heat from the windings directly to the outer wall of the aluminum housing. For installation, four through-holes for mounting screws are provided at the bottom of the tank. The clamping and drive module will operate in a vertical mounting position. The UPE 93 clamping and drive module can optionally be equipped with electronic monitors for oil level and oil temperature monitoring, an air filter, and complete hydraulic control.

R904100778 Overview of accessory modules for clamping and drive modules

1) Basic module "G": – Basic module with integrated relief valve for simple lowering and holding functions. – If basic module "G" is used, further stacking is not feasible. – For more details, see catalog "Control block types for clamping and drive modules. IH15A". 2) Directional valve module "W" 1): – Allows control designs using valves with porting surfaces conforming to DIN 24340 form A. – The number of directional valve modules depends on the discharge volume and pump displacement. – For more details, see catalog "Control block types for clamping and drive modules IH15A". 3) Seat valve module "S" 1): – The basic composition of a seat valve includes: • One relief valve block. • One or several control blocks. • One end block. – Control is designed according to the specific application. – The number of seat valve modules depends on the discharge volume and pump displacement. – For more details, see catalog "Control block types for clamping and drive modules IH106A". Directional valve modules and seat valve modules can be combined!

R904100778 Technical data for clamping and drive modules

When designing controllers with tanks, ensure that type-tested pressure relief valves protect the tank from impermissible overpressure. Type-tested pressure relief valves must not perform any control tasks, and their set pressure must be less than or equal to the maximum permissible working pressure of the tank. When using modules SPDB and SPDR at 9 xp (minimum working pressure), a filter with a filtration rating of 6 μm must be used. 1) Connection module type A (see page 74). 2) Connection module with pressure reducing valve type ADB (see page 75). 3) End module type E (see page 78). 4) Intermediate module type Z (page 76). Intermediate modules can also be combined with connection modules. Pos. 1 or can be combined with end module item 3. Length dimensions are calculated by summing the "X" dimensions of the directional valve modules (see pages 19 to 21) and poppet valve modules (see pages 31 to 72). Example: IH15BA006-1X / 07024AA / W220N9K4M01 Nominal size A IH15B assembly max. 14 l/min. With NG6 valve, 7 modules, consecutive numbering 24, variant AA, 220 V AC voltage, N9 manual operation, K4 connection type, sealing material Perbunan, connection type with pipe thread conforms to ISO 228 Part 1. Filter element assembly tool: - With pipe wrench Material No.: R904001048. Installation instructions for F30: - Turn the filter cartridge upward to the stop on the stop. Then rotate the filter cartridge approximately 1/3 turns. Installation instructions for DF30 and DF40: - Rotate the filter cartridge as far as possible. Then turn back approximately 1/8 to 1/243 turns.

R904100778 Level switches and temperature switches for clamping and drive modules

Level switch description: Level switches provide electronic monitoring of the hydraulic oil level. If the minimum oil level is reached, the contact opens and outputs a signal to the controller. Technical data: Max. voltage V 50 AC / DC. Max. current consumption A 0.25. Max. power consumption W 3.0. Protection class IP 65. Contact type normally closed contact. Temperature switch (option): The temperature switch protects the clamping and drive module from impermissibly high hydraulic oil temperatures. The temperature switch has a fixed switching point and switches when the hydraulic oil temperature reaches 80 °C. Switch-back hysteresis is approx. 10 K. Technical data: Rated current for 250 V AC 50/60 Hz (cos ϕ 0.95 / 0.60) A 2.5 / 1.6. Rated current for 50 V DC A 0.25. Contact type normally closed contact. Trip temperature °C 80 ± 43 K.
