Features • 3 Models: - Analog-In - Discrete I/O - Frequency/Discrete-In • Standard Modbus RTU slave over RS485 network interface, up to 115.2k baud • Low latency (< 1 mS) from Query end to Response start for high data throughput • Protected 24 VDC sensor power • Pluggable terminal blocks • DIN-rail mount • 24 VDC powered High-quality sensor and control I/O at low cost. All models directly connect to standard 2-wire RS485 networks of up to 31 Modbus slaves and a single Modbus master (PLC, PC, touch-screen, gateways, etc.). Ideal for building scalable systems: expand by adding ION modules to the network. Ideal for Hazard Monitoring systems: up to 12 temperature or shaft speed sensors per Analog-In module. ION Analog-In 12 precision 4-20 mA analog inputs convert with 1µA resolution Ideal for Hazard Monitoring (temperature, belt alignment, shaft speed) systems ION Discrete I/O 6 inputs - compatible with switches and NPN/sinking discrete-output sensors (e.g. prox, photo-eye, limit-switch) 6 relay outputs – Form-A (SPST) for controlling alarms, buzzers, motor starters, other relays, etc. ION Frequency/Discrete-In 12 dual-purpose inputs – compatible with all pulse/square-wave frequency-output sensors and signals (shaft-speed, flow, pressure) and all discrete-binary sensors/switches (prox, photo-eye, switch, relay etc.) All inputs are separately configurable and independent: acquire frequencies and discrete-binary states in any combination. High resolution (16 and 32-bit), high accuracy frequency measurement in any units (RPM, Hz and all user units)
