4 to 20mA, 0 to 20mA, 0 to 10V, 2 to 10V, 0 to 5V, 1 to 5V.
The Full RSP in Option Slot B also supports 0 to 100mv and
Potentiometer (2KΩ or higher).
±0.25% of input span ±1 LSD
Voltage ranges: 47KΩ nominal
Current ranges: 5Ω
Voltage input: will withstand up to 5x input voltage overload
without damage or degradation of performance in either polarity.
Current input: will withstand 5x input current overload in reverse
direction and up to 1A in the normal direction.
Slot A has basic isolation from other inputs and outputs.
Slot B has reinforced isolation from other inputs and outputs.
For 4 to 20mA, 2 to 10V and 1 to 5V ranges only.
Voltage-free or TTL-compatible
Connection to contacts of external switch or relay:
Open = SP1, Automatic Mode or Local setpoint
selected. Minimum contact resistance = 5KΩ,
Closed = SP2, Manual Mode, Remote Setpoint
selected, Latching Relay, Stored Min/Max/Time reset
(edge triggered) or Tare activate (edge triggered).
Maximum contact resistance = 50Ω.
2.0 to 24VDC = SP1, Automatic Mode, Local Setpoint
selected.
–0.6 to 0.8VDC = SP2, Manual Mode, Remote Setpoint
selected, Latching Relay, Stored Min/Max/Time reset
(edge triggered) or Tare activate (edge triggered).
0.25 second.
0.25 second.
Reinforced safety isolation from any source of
hazardous voltages.
