The TM5SAI4L is a Modicon TM5 series analog input module designed for use in modular PLC I/O systems. It provides four differential analog input channels capable of measuring both voltage and current signals.
Parameters
General
Module type: Analog input electronic module (Modicon TM5)
Number of input channels: 4
Supply voltage: 24 V DC (connected to the 24 V DC I/O power segment)
Power consumption: ~46 mA at 24 V DC; ~2 mA at 5 V DC TM5 bus; power dissipation ~1.11 W max
Weight: ~25 g
Protection rating: IP20
Analog Input Characteristics
Input signal types:
• Voltage differential: ±10 V DC
• Current differential: 0–20 mA and 4–20 mA
Input impedance: ≥ 20 MΩ (voltage); ≤ 400 Ω load (current)
Resolution: 12 bits with sign for voltage, 12 bits for current
Measurement resolution: ~2.441 mV for ±10 V; ~4.883 µA for 0–20 mA/4–20 mA
Sample duration: ~400 µs without filtering, ~1 ms with filtering
Accuracy & Stability
Typical measurement error: < 0.08 % of full scale at 25 °C (voltage and current)
Temperature drift: ~0.006 %/°C (voltage), ~0.009 %/°C (current)
Non‑linearity: < 0.025 % FS (voltage), < 0.05 % FS (current)
Common‑mode rejection: ≥ 70 dB DC and at 50 Hz
Isolation & Diagnostics
Isolation between analog channels and TM5 bus: ~500 Vrms AC (modules share common ground via bus)
No isolation between individual channels
Status LEDs indicate power, fault conditions, and per‑channel input status (overflow/underflow, conversion running)
