RLISRX2 – Ringline 2 Channel Relay Receiver I.S

Ringline Relay Receiver is a galvanically isolated, DIN-Rail mounted, 2 channel relay output receiver module, which decodes two discrete channels from the Ringline System. The decoded channels directly control the status of two change-over relay outputs for use in client circuitry.

Features

Simple, robust and functional.
Low Voltage DC Supply.
Status indication for “Power ON”, “Signal OK”, “Relay 1” and “Relay 2”.
Standard DIN rail mount enclosure.
Optical isolated between client circuitry and the Ringline field bus.
Direct connection to Intrinsically Safe Ringline without barriers.
Read only. Cannot interfere with the integrity of the Ringline Emergency Stop System.
High reliability in noisy environments.

Applications

This unit was originally designed to provide sequence control for the Ringline Emergency Stop System. In this format the normally open interlock of Relay 1 is wired in series with the normally closed interlock of Relay 2 to provide a dual channel ‘Run’ permissive command mounted in any equipment to be sequenced. It may however be used as two general purpose receivers for any two channels on the Ringline system. It may be used on either Ringline 128 or Ringline 192. Each relay output provides a single pole change-over contact.
