Chromalox 1603 User's Manual 5
The SSR Drive Output is a time proportioning output.
Logic Level 0:Vout < 0-5 Vdc
Logic Level 1:14V ± 20% @ 17mA
+24V ± 20% @ 1mA
Maximum = 17mA
Notes:
1.This output is not isolated. An external solid state
relay with 2600V isolation must be used to isolate
the controller output and power supply for CE
compliance. The Chromalox Series 4115, 7710,
4001, and 4003 meet these isolation requirements.
2.To determine Output #1 output type, check the tag
on your controller and compare it to the model
identification table on page ii.
Inductive Loads (continued)
Warnings:
When a relay output is used to drive an inductive
load, it is suggested that you connect an external
snubber network (RC) across the terminals using
Chromalox P/N 0149-01305.
