AutoLog® AL-8 PLC
Compact OEM-PLC · 4 DI / 2 DO / 2 RO / 0-2 AI
AL-8 adds on-board analog inputs and a digital-output pair to the AL-4 base. Four digital inputs, two digital outputs, two relay outputs and zero-to-two analog input modules with the standard AutoLog plug-in module catalogue: Pt100, KTY10, NTC, 0..5/10 V, ±10 V, 0..5/20 mA, 4..20 mA, RMS 40 / 25 / 0.25 VAC. Two serial ports — Modbus RTU master/slave on both. Optional integrated GSM modem (AL-8 w GSM) reduces operating temperature to 0 to +55 °C.
