10 CONFIGURATION OF AMC8 / IOC8T CARDS
This chapter describes the connectors on the IOC8T card. These are accessed from the rear
of a VM600 MPS rack.
Typical sensor connection diagrams are included for thermocouples, RTD devices as well as
other sensors providing a voltage-based or current-based signal.
Information is also given on attributing specific alarm signals to specific relays on RLC16
cards using the Open Collector Bus and the Raw Bus.
10.1Definition of screw terminals on the IOC8T card
The IOC8T panel (rear of rack) contains four contact strips, identified as J1 to J4.
Strips J1 to J3 consist of a socket and a mating connector, which contains either 24 or 20
cage clamp terminals (see Figure 10-1). The terminals can accept wires with a cross section
of between 0.08 and 1.0 mm

. Strip J4 consists of a socket and a mating connector, which
contains 12 screw terminals. The terminals can accept wires with a cross section of
1.5 mm
2
.
The mating connectors are labelled “SLOT xx Jn” (where xx is the slot number and Jn = J1,
J2, J3 or J4) to enable the connector to be matched to the correct socket of the correct card.
Each socket and mating connector can be equipped with a mechanical key system to prevent
incorrect connection.
Further details on these screw terminal contacts can be found in Table 10-1.
