Specifications
Storage Temperature
-67°F to 167°F (-55°C to 75°C)
Standard Inputs/Outputs
Two 0/4 to 20 mA isolated outputs, 550 S maximum load
Optional Inputs/Outputs
There are six additional slots available for any
combination of the following I/O boards:
• Analog outputs: Select up to three additional output
boards, each with four isolated 0/4 to 20 mA outputs,
1000 S maximum load
• Analog inputs: Select up to three boards of one of the
following types:
- Analog input board with two isolated 4 to 20 mA
inputs and 24 V loop power
- RTD input board with two isolated, three-wire,
RTD inputs; span -148°F to 662°F (-100°C to 350°C);
100 S
• Totalizer/frequency outputs: Select up to three
totalizer/frequency output boards, each with four
outputs per board, 10 kHz maximum. All boards allow
software-selectable functioning in two modes:
- Totalizer mode: Pulse per defined unit of parameter
(e.g., 1 pulse/gal)
- Frequency mode: Pulse frequency proportional to
magnitude of parameter (e.g., 10 Hz = 1 gpm)
• Alarm relays: Select up to two boards of one of the
following types:
- General purpose: Relay board with three Form C
relays; 120 VAC, 28 VDC maximum, 5 A maximum;
DC 30 W maximum, AC 60 VA
- Hermetically sealed: Relay board with three
hermetically sealed Form C relays; 120 VAC, 28 VDC
maximum, 2 A maximum; DC 56 W maximum,
AC 60 VA
