| Manufacturer | ATC Diversified |
| Manufacturer Product Number | ISO-120-AFN |
| Description | Intrinsically Safe Relay; Class I/II/III Div 1; 1-Ch; Non-latching; 120V AC |
| Datasheet | Download Datasheet |
The ATC Diversified ISO-120-AFN is an intrinsically safe relay with SPST-NO per channel output and rated 5 A resistive at 24 or 120 V AC per channel; 278 VA inductive, driven by a 120V AC input.
It lets a switch or sensor in a hazardous location (Class I, Groups A-D; Class II, Groups E-G; Class III (UL913 intrinsically safe inputs)) control a load in the safe area.
It has one channel: an isolated input and output.
Logic: non-latching.
Response time: 6 ms operate, 2.5 ms release.
It has Surface Mount (epoxy sealed) mounting and Screw Terminal (#8-32) terminals.
