Practical handbook for relay protection engineers | EEP
The RLY-108 has a galvanic isolation barrier between relay contacts and the control circuitry to protect the control system and power supply from potentially hazardous voltages.
Safety monitoring relays Sr107, 108 & 109AD
For a full explanation of the circuit operating principle and fault detection, see “Common Circuit Examples” in The Safety Library Section of this catalog on page A62
AN-108_December-22-2012
Because the integrated current limiting circuitry instantaneously limits current through the relay, it is in effect self-protecting. In addition to protecting itself, it also protects any circuitry beyond the relay
B840-108 Relay Output, Overview
The B840–108 relay output module converts signals from the 800 series Ourbus to eight independent relay outputs. Each output is capable of driving relays, pilot lamps, or other loads up to 2 A. The
