The APM series modules provides easy installation and maintenance efficiency for monitoring process signals, such as temperature, voltage and current. With the ability to connect up to 31 modules, the APM Series features both standar RS-485 Modbus RTU, Ethernet Modbus TCP and Wi-Fi connectivity options.

The multi-channel and compact design of modules (17.5mm width) maximizes the space use and the push-in terminal design saves time for wiring, system expanding and maintenance.

Embedded expanding connecting points inside the modules, actively connect the power supply and the communication ports of the modules in parallel, to provide a more efficient and flexible installation.

■ Main features:
- Modules expanding limit up to 31 units.
- Multi-module power supply: when several modules connect in parallel, the power input of each module will combine as one connection. Therefore, it's easy to energize the whole module group in parallel by importing power supply to any one of the modules.
- Multi-module RS-485 communication: when several modules connect in parallel, the RS-485 port of each module will combine as one connection. RS-485 communication could be imported from each port of both ends of the module group.
- DIP switches on front panel for communication setting.
- LED indicators for power, system and importing status provides a convenient way to monitor system operation, troubleshooting and maintenance.
- Detachable terminal block design allows pre-wired cable, and is able to exchange the module in system without removing the existed wiring so as to optimize system repair and maintenance.
- 18~36 VDC wide voltage power supply for more flexible application and safety.
