M-System

Limit Alarms 
A limit alarm is used to provide one or more relay/contact outputs when a monitored process signal goes out of
Pre-selected high or low limits. Typical applications are:

Trouble warning (annunciators)
Emergency shutdown
ON/OFF control

M-System limit alarms are available with wide combinations of process signal I/O and power input, featuring also various setpoint access means.

Programmable alarms feature enhanced programmable functions such as failsafe operation, deadband, delay time, latching relay and others, while analog alarms feature basic but easy setting.

Power Transducers 
Transducers for electrical measurement are an essential part of any monitoring, measuring, or controlling system where electrical quantities are involved. For example, a power transducer monitors both AC current and voltage to measure/calculate true electrical power delivered to a load and converts it to a DC voltage or current signal proportional to the measured power.

Multi power monitors are capable of open network interface such as Modbus RTU, Modbus TCP/IP, CC-Link and
LONWORKS, which are commonly used for modern energy measurement and management systems to achieve energy saving.

Remote I/O
Remote I/O supports DCS/PLC systems by expanding I/O flexibility in addition to providing all full channel-to-channel isolation. It communicates directly to the PLC and DCS via industry standard open-protocol networks.

Remote I/O can be also used as stand-alone distributed I/O communicating with popular HMI software. It can be located remotely in the field, or within an instrumentation cabinet such as test stands.

The flexibility and scalability of M-System’s Remote I/O supports future system upgrades with full isolation between power-communication-I/O and between analog channels. Economical non-isolated analog modules are also selectable.

Applications include: signal concentrator, data collection in flow and level monitoring, injection molding monitoring and control, test stands and prototyping, glass furnace temperature control, paint booth environment reporting, pharmaceutical processes, and assembly line discrete ON/OFF.

Lightening Surge Protectors 
M-System Surge Protectors absorb only the lightning surges with no interruption of the instrumentation signal.

They are designed for the rugged industrial environment. Products range from the standard factory floor signals such as 4-20mA, thermocouple, RTD and strain gauge to filtering and protecting the AC Power in instrument panels.

Protecting sensors, signal and power lines, communication networks
Excellent protection by multi-stage SPD: extra protection by a series resistance with diodes to limit current flow in addition to the discharge element at the first stage
Each model identified by specific sensors or devices to be protected; with carefully chosen specifications to provide maximum protection
One-port surge protectors are also available for power line protection
