RY1 Relay Input Card
Brand: Yokogawa
This unit receives contact signal from the field and outputs 2 contact signals (1 for use of DCS status card input and the other is re-transmit contact signal) isolated electrically from the field. One unit stores 2 channels.
Features- Output contact consists of 2 contacts; 1 for DCS contact and the other for re-transmit contact (transfer contact) of current capacity 1A
- Electrically isolated between field input and power supply since DC/DC converter for relay driving power supply is installed
- Furnished with test switch convenient for debugging of DCS or checking operation and LED for status display
