| Loop Control | Automatic tuning type: Pre-tune and self-tune Proportional bands: 0 (inactive), 0.5 % to 999.9 % of input span with 0.1% increments. Two proportional bands available for duplex mode Reset: Off or from 1sec. to 99 min 59 sec. Rate: From 0 sec. to 99 min 59 sec. Manual reset: from 0 to 100 % of output (single output), from –100 % to 100 % of output (dual output) Deadband: ± 20 of PB1 + PB2 ON/OFF hysteresis: 0.1% to 10.0 % of input span Auto/manual mode: Front key selectable with bumpless transfer between automatic and manual mode Cycle times: Up to two cycle times available for time duplex control Selection: 0.5, 1, 2, 4, 8, 16, 32, 64, 128, 256, or 512 seconds Setpoint ramp: From 1 to 9999 engineering units per hour |
| Retransmission Output | Any output can be selected to retransmit the process value or setpoint as a linear (current or voltage) output |
| Digital Input (optional) | On contact the digital input will switch between SP1/SP2 or Auto/Manual or DC100L Remote Reset |
| Communication Interface | RS485 – ASCII or Modbus RTU (selectable from the menu) Baud rate: 1200, 2400, 4800, 9600 or 19200 baud Link characteristics: 32 drops maximum, ASCII or Modbus protocols, two wires |
