IO Cards
Modbus RTU IO expansion cards over RS485
Generic Modbus Analog / Digital IO cards for gateways, PLCs and SCADA masters. Voltage, current, digital and pulse inputs with relay outputs — configurable addressing, scaling and resolution over RS485.
10
Digital Inputs(WT32i · 0–24 V)
8
Digital Outputs(WT32i · Modbus coils)
6 + 6
Analog Inputs(WT36i · 0–10 V / 4–20 mA)
32-bit
Pulse Counters(0 – 999999)
RS485 · Modbus RTU
Slave Interface
12 – 24V DC
Wide Voltage Input
Standard RTU slave — works with any Modbus master
Address, scaling & resolution set via holding registers
Voltage, current, digital & pulse on one card
Outputs driven directly by Modbus coils
RX · TX · CON · PWR diagnostics at a glance
Configurable failsafe outputs on WT32i
Analog Modbus IO Card
Analog Modbus IO Card
Analog / Digital IO Card
No programming required — device ID (1–247), baud rate (2400–115200), parity, scaling and input modes are all set through standard Modbus registers. Works with any Modbus RTU master, including all Wiman gateways.
