Intelligent relay card IRC4
FEATURES
» From the Vibro-Meter® product line
» 8 relays can be combined as 4 DPDT or 8 SPDT
» Each relay is controlled by a specific logic equation, which can be a combination of AND, OR, NOT or VOTE (x between y) operators
» Each relay can be latched, with reset controlled by an external discrete signal interface (DSI) input or by a specific logic equation
» 64x raw bus lines, 16x OC bus lines and 6x external DSI inputs can be used as terms of the equations
» Each relay can be set to NE or NDE
» Delays can be set on each relay to ensure glitchfree operation
» 4 external DSI inputs can be used as general purpose inputs for the logic equations
» External AR and DB DSI inputs act as alarm (latch) reset and danger bypass
» Fully software configurable
» Non volatile configuration
» Screw terminal strip connectors (32 terminals)
» Ensures EMI protection for all inputs and outputs
» Live insertion / removal of cards (hot-swappable)

Relay characteristics

Relay names : RL1 to RL8
Type : PE014005
Contact arrangement : 1 x NO / NC contacts per relay (SPDT).
Relay contacts RL1-RL4 are available on the J1 connector and RL5-RL8 are available on J2 connector.
Nominal rated voltage : 250 VAC
Nominal rated current : 5 AAC
Maximum breaking capacity(without contact protection) : 1250 VA

Operate / release / bounce time : Typically 8 / 8 / 6 ms
Dielectric strength test voltages
• Between open contacts : 1000 VAC
• Between contact and coil : 4000 VAC
Mechanical life : 15 x 106 operations
Electrical life : >105 operations

DSI control signal inputs
Operating principle : Detection of an open or closed circuit on the input
Alarm reset (AR) : A closed contact between the AR and GND inputs resets latched alarms
Danger bypass (DB) : A closed contact between the DB and RET inputs allows the operator to inhibit the danger relay outputs
Discrete inputs
Number of inputs : 64x raw bus, 16x OC bus, 4x general purpose DSI inputs, including DB and AR
Input impedance : Raw bus and OC bus ≅ 1 MΩ.
DSI ≅ 10 kΩ.
Raw bus and OC bus threshold level : TTL
DSI threshold level : Ground (true) ≤3.0 V.
Open (false) ≥4.5 V (the IRC4 includes an internal pull-up to +12 V)
