Optional features
Heater burnout alarm [W]
This function watches the heater current with a CT (current transformer), and
detects the burnout.
Heater rated current must be selected from 5A, 10A, 20A and 50A.
The heater burnout alarm will use the alarm 1 output
Serial communication [C5]
Various setting status changing, reading and setting of the TP Series can be
performed from external computer, HMI or PLC.
Communication interface Based on EIA, RS-485
Communication method Half-duplex communication start-stop synchronous
Data transfer rate (2400/4800/9600/19200bps) Select by key operation
Communication protocol Based on IMO standard protocol or Modbus
(Selectable by key operation) When Modbus is selected, RTU mode or ASCII
mode can be selected by key operation.
Number of connectable units A maximum of 31 units per communication port
Communication error detection Parity check and Checksum
