Compared with DTA series, DTB is additionally equipped with linear voltage signal output and dual output control, capable of executing heating and cooling controls simultaneously in a temperature control system and fast reaching the target temperature.
Blower coil pipe in central air-conditioning system, heating system.
PID / On-Off / manual input / programmable control modes
2 groups of outputs to auto-tuning 2 groups of PID parameters
Able to connect to various thermocouples (B, E, J, K, L, N, R, S, T, U, TXK), platinum RTD (PT100, JPT100), analog current (0 ~ 20mA, 4 ~ 20mA) and linear voltage (0 ~ 5V, 0 ~ 10V)
Maximum 3 groups of alarm switches are available, with 18 alarm modes each
Celsius or Fahrenheit temperature display
2 key lock functions (1. lock all keys; 2. lock only function keys, up/down keys are still workable)
