VM600 IOC4T input/output card - Bo mạch IOC4T
High-quality, high-reliability interface (input/output) card for the MPC4 and MPC4SIL machinery protection cards used by VM600 rack-based machinery monitoring systems. The IOC4T card supports 4 dynamic channels and 2 tachometer (speed) channels, all of which are independently configurable. An IOC4T interface card is installed in the rear of a VM600 ABE04x rack, directly behind an MPC4 card or MPC4SIL card, to form a card pair.
Features
- Input/output (interface) card for an MPC4 or MPC4SIL card – supports 4 dynamic channels and 2 tachometer channels
- Differential signal input with sensor power supply output per dynamic channel and per tachometer channel
- Differential buffered (raw) transducer output per dynamic channel
- DC output configurable as current-based signal (4 to 20 mA) or voltage-based signal (0 to 10 V) per dynamic channel
- 4 configurable relays with two contacts available per relay, and alarm reset (AR), danger bypass (DB) and trip multiply (TM) control inputs
SPECIFICATIONS
Vibration inputs
Filtering : Filtered for protection against electromagnetic interference (conforms to EC standards).
Refer to the MPC4 data sheet for additional specifications.
Vibration outputs
Filtering : Filtered for protection against electromagnetic interference (conforms to EC standards).

Speed / phase reference inputs
Filtering : Filtered for protection against electromagnetic interference (conforms to EC standards).
Refer to the MPC4 data sheet for additional specifications.
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 RET 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
Trip multiply (TM) : A closed contact between the TM and RET inputs, multiplies the alarm levels by a scale factor (software settable).
When TM is open, the scale factor is not taken into account.
Alarm outputs
Quantity and type : 32 outputs on rack backplane bus, for use by the VM600 relay cards: the IRC4 intelligent relay card and the RLC16 relay card
DC outputs
Number of outputs : 4 per IOC4T card
Signal range : 0 to 10 V or 4 to 20 mA (selectable by jumper on IOC4T for each output).
Note: An output range of 0 to 23 mA is available for applications where the current signal is also used to monitor open and short circuits.
Accuracy : ≤ ±0.5%
Linearity error : ≤ ±0.5%
Admissible load on output : > 100 kΩ for voltage output < 325 Ω for current output
Relay characteristics

The selected contacts are available on J2.
Nominal rated voltage : 250 VAC
Nominal rated current : 5 AAC
Maximum breaking capacity (without contact protection) : 1250 VA
