AC800M DI831 3BSE013212R1 2*8-channel digital input 48V d.c,SOE

The AC800M is a key component of the Compact Products 800 series, a modular, rail-based controller that includes a CPU, communication module, power supply module and a range of accessories.The AC800M controller is programmed and configured with Compact Control Builder programming software, which allows the AC800M controller to be used for a variety of control applications. The reusable code and library file features also make the AC800M applications easier to configure and build.

From basic logic operations to advanced control or both, from a small number of I/O points to thousands of applications, from local to remote installations, the AC800M can handle it all. One of the common features of the AC800M module is its low power consumption, which makes heat dissipation virtually irrelevant and allows for easy and compact installation. In most cases, AC800M controllers can be installed airtight in cabinets without fans, openings, air filtration, or similar equipment. As a result, many potential failure factors are eliminated, ensuring high reliability of the controller.

AC800M controller performance
-Integrated power supply unit, CPU processor and memory on CPU board
-Five different controller types for users to choose from
-PM851, PM856, PM860, PM861, PM864, PM865 respectively
-Memory storage for operating firmware, control unit hardware configuration information and applications
-Support 12 fieldbus modules expansion
-Integrated 2 Ethernet interfaces, 2 RS232C interfaces, ModulBus electrical and fiber optic expansion interfaces
Supports redundancy settings to reduce point-of-failure errors and ensure control system operational efficiency
-Up to 16 tasks, minimum task cycle 1ms, SOE sequential event resolution <1ms
CPU can realize controller level communication through Ethernet interface, 2 Ethernet ports can be set as redundant, and built-in redundancy switching program is used to improve system reliability.
Communication

There are two types of connections between controllers and I/Os:
-Local I/O: using Modulebus (electrical/fiber optic) communication lines, with a maximum of 8* local I/O stations per controller;
-Remote I/O: remote I/O connection using Profibus DP fieldbus extension, supporting a maximum of 98 remote stations;
-Longest distance Cable 500m (500Kb/s)
-Multimode fiber 2KM (12Mb/s)
* Non-redundant for 8 local I/O stations
Redundant for 7 I/O stations
As an important component of the control network, the AC800M controller supports two modes of operation, redundant and non-redundant, and two modes of communication services, client/server. The client service enables communication between controllers and with the engineer station software. The OPC Server service also enables data communication with third party software and systems such as HMI.
The AC800M controller supports a variety of popular communication protocols including MasterBus 300, COMLI, Modbus, and Siemens 3964R, allowing easy communication with other controllers, automation systems, and field devices. external devices.
