for further information.
Discrete signal interface (DSI) inputs

Control signal
• Alarm reset (AR) : A closed contact between the DSI AR and DSI RET inputs resets
(clears) the alarms latched by the MPC4/IOC4T card pair.
Note: The alarm reset input (DSI AR) is edge-sensitive and a high-tolow transition is required to activate the reset.
• Danger bypass (DB) : A closed contact between the DSI DB and DSI RET inputs inhibits
(bypasses) the danger relay outputs
• Trip multiply (TM) : A closed contact between the DSI TM and DSI RET inputs multiplies
the alarm levels by a scale factor (software configurable), to
enable adaptive monitoring.
Operating principle : Detection of an open circuit or a closed circuit on the input
Alarm outputs
Alarm relays : 4 per IOC4T card.
The MPC4 card can drive the four local relays on the IOC4T card,
as well the relays on RLC16 relay cards and/or IRC4 intelligent relay
cards using the VM600 rack’s Raw bus or Open Collector (OC) bus.
For IOC4T card relay features, see Relay characteristics on page 4.
For further information on RLC16 or IRC4 relay cards, refer to the
corresponding data sheet.
Note: In a VM600 rack (ABE4x), the Open Collector (OC) bus and/or Raw bus can be used to connect up to
32 outputs from an MPC4/IOC4T card pair to RLC16 relay cards or IRC4 intelligent relay cards in the same rack,
if additional relays are required.
