Optional Terminal Block Kit (Item# Kt108) - SeaLevel PLC-16.PCI User Manual

Optional Terminal Block Kit (Item# KT108)

Another option for termination of the PLC-16.PCI is the Terminal Block Kit (Item#
KT108). This kit includes an HD44 Male to HD44 Female six-foot cable (Item#
CA185) and a 28-Pin Terminal Block (Item# TB08-KT). The silk screen with
diagram is shown on the following page.
The CA185 cable is wired straight through, one-to-one.
The terminal block groups the common connections of the PLC-16.PCI into groups
of four as shown:

RC1 (Relay Common 1) ties together the ground pins for physical relays K1 –
K4 (logical D0 – D3) e.g.: HD44 pins 16,17,18 and 34 are connected to simplify
field wiring

RC2 (Relay Common 2) ties together the ground pins for physical relays K5 –
K8 (logical D4 – D8) e.g.: HD44 pins 19,20,21 and 22 are connected to simplify
field wiring

The other eight screw terminals in each group (16 total) are used to wire to the
NO (Normally Open) or NC (Normally Closed) side of the relays. These are
labeled K1 – K4 and K5 – K8

IC1 (Input Common 1) ties together one side of the input pins for D0-D3 and IC2
(Input Common 2) ties together one side of inputs D4-D7 to simplify field wiring

The other four pins in each group (8 total) are used to wire to the inputs. These
are labeled ID0 – ID3 and ID4 – ID8
