OVERVIEW OF VM600
Mk2
MACHINERY PROTECTION SYSTEM (MPS) HARDWARE
2.3.1 IOC4
Mk2
module connector pinouts
As shown in Figure 2-3, the IOC4
Mk2
panel (rear of rack) contains three connectors, identified
as J1, J2 and J3.
Each connector consists of a male connector (socket on module) and a mating female
connector (plug on wiring):
• J1 (top) is a 24-pin connector used to connect inputs (analog signals) for the dynamic
channels (CH1 to CH4) and the auxiliary channels (AX1 and AX2).
• J2 (middle) connector is a 36-pin connector used to connect inputs and ground reference
(digital signals) for the DSI control signals (AB, AR and TM), outputs (buffered “raw”
signals) for the dynamic channels (CH1 to CH4) and the auxiliary channels (AX1 and
AX2), outputs (digital (pulse train) signals (TTL-level)) for the auxiliary channels (AX1
and AX2), and outputs (analog signals) for the analog DC outputs.
• J3 (bottom) connector is a 16-pin connector used to connect outputs (contacts) for the
common circuit fault relay (FAULT) and the user-configurable relays (RL1 to RL4).
Detailed information on the IOC4
Mk2
module’s connector pinouts (definition of terminals) are
given in Table 2-4, Table 2-5 and Table 2-6.
