Bosch Rexroth UPE2-1X/1, 1R1, 25/3AN-B1V-002+00992206 Part No. R904100628 Clamping and Drive Module Distribution

R904100628 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 environmental 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 operates in a vertical mounting position. Optionally, the UPE 128 clamping and drive module can be equipped with electronic monitors for oil level and oil temperature monitoring, air filters, and complete hydraulic control.

R904100628 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 IH141A". Directional valve modules and seat valve modules can be combined!

R904100628 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: Maximum voltage V 50 AC / DC. Maximum current consumption A 0.25. Maximum 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 set switching point and switches when the hydraulic oil temperature reaches 80 °C. Switch-back hysteresis is approximately 10 K. Technical data: Nominal current (cos ϕ 0.95 / 0.60) A 2.5 / 1.6 at 250 V AC 50/60 Hz. Nominal current A 0.25 at 50 V DC. Contact type: Normally closed contact. Trip temperature °C 80 ± 78 K.
