Toho Seisakusho RX-1003PUI type Balancing Relay

Made in Japan
Manufacturer: Toho Seisakusho
Model:RX-1003PUI type

Features

RX-1003PUI

The opening signal can be output using a constant current method of 4 to 20 mA DC.

Using SSR for the motor drive offers a semi-permanent lifespan compared to relay contacts.

You can use the motor across a wide range of ratings.

The power supply supports AC24-240V±10% and can directly drive capacitor motors up to AC3A.

The input signal (4 to 20 mA DC) and (1 to 5 V DC) or (0 to 10 V DC) can be switched using a jumper pin inside the main unit.

You can switch between direct operation and reverse operation by using a jumper pin inside the main body.

By adjusting the span (gain = slope) and zero (moving the zero point up and down) using the internal amplifier, you can change the opening characteristic for input signals.
