Specification
Options
Pulse Input (optional) 4 isolated inputs per board, frequency – 1Hz to 25kHz, updated once per sec. Input: Low <
1V, High >4V to <50V or Volt free input: Low = short circuit, High = open circuit.
Alarm Outputs
(optional)
Programmable alarm set points (6 per pen) can be configured to activate up to 16 outputs.
Update rate: 200 ms for all alarms. Number/Type:
• 4 or 8 relay contacts SPDT, 3A 240VAC, 3A 24VAC/DC, 0.2A 240VDC (non-
inductive, internally suppressed)
• 8 I/O or 16 I/O - SPNO 1A 24VDC (non-inductive, internally suppressed)
Activation: Fully programmable internal alarm levels. Assignable to any relay output.
Digital Input/Output 8 I/O or 16 I/O: all channels may be selected freely as either digital inputs or outputs.
The Digital I/O card also has 4 channels that can be set as pulse inputs (channels 1 to 4). The
operating frequency for pulse inputs on the Digital I/O card is 1kHz max.
4 relay outputs: all four channels are relay outputs only.
8 relays/ 2 DI card: two outputs can be configured for use as digital inputs: A digital input is
provided by a volt free contact between the normally open (NO), and the common (C),
terminals of an output relay. If the 2 Digital inputs are used only 6 relay outputs are available.
Closed <500 ohms, Open >300 kohms.
Analogue Outputs
(Re-transmission
Outputs)
(optional)
2 or 4 re-transmission outputs available; a pen drives each output. Analog inputs, totalised
values or any mathematical result can be re-transmitted.
Update Rate: 250 msec all channels Accuracy: ±0.1% 0-500Ω load, +/-0.25% 500Ω 1KΩ load
Type: 0 to 20 / 4 to 20 mA Maximum Load Resistance: 1000 Ohms
Resolution: 0.002% Isolation: 300VAC
Transmitter Power
(optional)
200mA @ 24VDC ± 3VDC.
