Bosch Rexroth UPE2-1X/1, 1R1, 25/4ANT-B1V+R920051419 Part No. R920051420 Clamping and Drive Module Distribution

R920051420 Bosch Rexroth UPE2 clamping and drive module (51142) IH15A control modules are used to implement complete hydraulic control. They can be equipped and assembled individually. Directional valve modules and seat valve modules can be combined with each other, and the control modules can be directly connected to the clamping and drive module UPE2. However, with the aid of external accessory modules, the hydraulic control unit can also be installed in any system. The RBAIH15A type reduction module enables the IH15A module to be directly mounted on the container cover of conventional drives. Using the RIH15AR type pressure reducing module, the hydraulic control unit can be connected to the control devices of the IH15B control module series. This module is preferably designed for hydraulic control units of small-volume consumers with a volume flow not exceeding 284 l/min. They are interconnected by two tie rods.

R920051420 Overview of Accessory Modules for Clamping and Drive Modules

1) Basic module "G": – Basic module with integrated relief valve for simple lowering stroke and holding pressure functions. – If the basic module "G" is used, further stacking is not feasible. – For more details, see the catalog "Control Block Types for Clamping and Drive Modules IH15A". 2) Directional valve module "W" 1): – Design that allows control using valves with port mounting 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 the catalog "Control Block Types for Clamping and Drive Modules IH15A". 3) Seat valve module "S" 1): – The basic composition of the 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 the catalog "Control Block Types for Clamping and Drive Modules IH137A". Directional valve modules and seat valve modules can be combined!

R920051420 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. 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: 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. Trip temperature °C 80 ± 74 K.
