Notes
Temco Control's T3E-886 I/O expander.
6 relay outputs
8 analog outputs (0-10V)
8 analog inputs (0-10V, 4-20mA, Thermistor or on/off)
Supports Modbus/RTU and /TCP
Connect (RTU):
ezeio D0 -> 485-
ezeio D1 -> 485+
ezeio 0V -> GND
ezeio +V -> Power+ (optional)
Default address 254, 19200bps
Write to holding register 6 to change address/unit
Write to holding register 15 to change speed
0=9600, 1=19200
Notes:
- When using /TCP, the /RTU address is the unit.
- When in 4-20mA mode, the inputs switch in the shunt resistor for 50ms every 450ms. Loop powered deviced may have an issue with this.
- The /RTU bus will sometimes miss a message shortly after the output state change.
- Output switches must be in the "A" position for remote control
