Definition of screw terminals on the IOC4T card
CONFIGURATION OF MPC4 / IOC4T CARDS
9 CONFIGURATION OF MPC4 / IOC4T CARDS
This chapter describes the connectors on the IOC4T card. These are accessed from the rear
of a VM600 MPS rack.
Typical connection diagrams are included for measurement signal sensors (such as
accelerometers and proximity probes) and speed signal sensors.
Information is also given on attributing specific alarm signals to specific relays on RLC16
cards, and using the Open Collector Bus and the Raw Bus.
9.1 Definition of screw terminals on the IOC4T card
The IOC4T panel (rear of rack) contains three terminal strips, identified as J1, J2 and J3 (see
Figure 9-1). Each strip consists of a socket and a mating connector, which contains 16 screw
terminals. The screw 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 or J3) 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 9-1.
