The main module can be powered by 230 V or 24 V. It contains three digital inputs that respond to the supply voltage level. It also contains six universal inputs, which are isolated from the power supply and outputs with a common ground terminal.
These inputs allow the connection of the following signals:
• pulse up to 30 V
• impulse - contact, NPN open collector
• analog, voltage up to 30 V
• analog, current up to 20 mA
• analog, resistance up to 3900 Ω
• analog, Pt 100, Pt 1000, Ni 1000
• analog, T / C - B, E, J, K, L, N, R, S, T, XK
• analog, KTY81-2xx
