MX2NC PLC User Manual
Thank you for choosing the Coolmay MX2NC series PLC. This manual mainly explains
the features, general specifications and wiring methods of MX2NC series PLC. Detailed
programming information please refer to "CoolmayMX2NC PLC Programming Manual".
MX2NC series PLC has the following features:
1. Highly integrated and super functional. Maximum support 16 digital input and 16
digital output.
2. Support multi-channel high-speed counting and high-speed pulse functions, high-
speed counting normally 6 channels single-phase 10KHz or 2 channels AB (Z) phase
10KHz; high-speed pulse normally 4 channels 10KHz.
3. Support special encryption. Setting 12345678 as password can thoroughly prevent the
data from being read. (Note:Only supports 8-bit password encryption)
4. Support for external interrupts and watchdog functions.
5. Use DIN rail (35mm width) to install.
6. Use pluggable terminals with a pitch of 3.5mm, which is convenient for wiring.
