B&R X20CM0985 brand Programmable Logic Controller Module

Programmable logic controllers, operating and monitoring devices (e.g. industrial PCs,

Power Panels, Mobile Panels etc.) as well as the uninterruptible power supplies from

B&R have all been designed, developed, and produced for conventional use in industry.

They were not designed, developed and manufactured for any use involving serious

risks or hazards that could lead to death, injury, serious physical damage, or loss of

any kind without the implementation of exceptionally stringent safety precautions.

In particular, such risks and hazards include the use of these devices to monitor nuclear

reactions in nuclear power plants, as well as flight control systems, flight safety, the control

of mass transportation systems, medical life support systems, and the control of weapons

systems.

The module has a compact size and combines a power measurement module that has

special features with a synchronization unit that is able to meet all demands.

The measurement unit's 3 current inputs are suitable for both X: 1 A and X: 5 A current

transformers. Overcurrent resistance and the high resolution of the measurement unit

round off its features. For the voltage inputs, the value range can be configured between

480 VAC and 120 VAC.

The area of use includes 4-wire AC networks with a phase voltage up to 480 VAC and

3-wire systems, whereas L2 can be grounded (V-connection). The module can also handle

Aron measuring circuits.

The resulting measured values include the pure phase current; line-to-line voltage or phase

voltage; the effective, reactive and apparent power parts; the mains frequency; the power

factor and much more. In addition, peak values and energy meters are stored on the module

in nonvolatile memory. Depending on the configuration, it is also possible to use a digital

output as a pulse encoder for an external energy meter.
