D-2 2408 and 2404 Controller
1. EXAMPLE WIRING DIAGRAM (FOR MODE 1 & 2 OPERATION)
Hardware Required
1. SSR type TE10/PDS2 OR
2. Intelligent current transformer type PD/CTX + contactor or zero voltage switching SSR
2408 or 2404 controller configured for PDS mode 2 option using logic output. This module
must be fitted in module position 1. (order code M2).
Figure D.1 Connections for Mode 1 & 2
WARNING!
Take care that the controller is correctly wired for the mode of operation which is
configured. Failure to do so may be hazardous in some situations.

Alternative current regulator
arrangements:-
The TE10/PDS2 contains integral power
regulator and intelligent PDCTX
The PDCTX can be supplied separately for
use with any SSR or logic thyristor unit as
shown in the diagram below.
The output drive capability of the PDCTX is
5V at 7mA maximum
