Product information
Overview
Key Features
- Analog inputs: 6 analog inputs with potential separation between channels, in groups of 1, and between channels and the backplane bus.
- Thermocouple signals: Supports thermocouple types B, E, J, K, L, N, R, S and T; thermocouple input range is supported.
- Voltage input ranges: Supports -1 V to +1 V, -250 mV to +250 mV, -50 mV to +50 mV, -500 mV to +500 mV and -80 mV to +80 mV; input resistance is 10 MΩ for the listed ranges.
- Resolution and conversion: Maximum resolution is 16 bit including sign with Two's complement; basic conversion time is 30 / 50 / 60 / 300 ms.
- Diagnostics and alarms: Has parameterizable diagnostics, channel-by-channel diagnostic alarms, parameterizable limit value alarms and parameterizable hardware interrupts.
- Connection and isolation: Requires a 40-pin front connector; isolation is tested with 2 500 V DC. The product lifecycle is Product cancellation.
