News - The Honeywell Modbus Read-only Firewall is unique in the industry as it is the first fixed configuration firewall to use Tofino's "deep packet inspection" technology against the popular SCADA protocol, Modbus TCP.



Tofino MODBUS Read-Only firewall



This technology scans every network message, only allowing a very limited set of valid Modbus "Read-only" commands through to the safety system.







LED Series is a range of versatile, high-performance, surge protection devices.



LED Series surge protection - MTL Instruments



The fast acting circuitry will protect equipment from damaging electrical transients and disturbances. Fully automatic in operation the LED Series reacts immediately, clamping voltage surges without causing undue leakage losses under normal operation.
