SPM-H

About the SPM-H

The SPM-H Harsh Environment Starting and Protection Relay is essentially the same functional product of the SPM Standard Starting and Protection Relay, although the SPM-H Unit here comes equipped with a robust conformal base circuit board coating to allow it to function in harsher and less forgiving environments. Of course, the SPM-H Relay should primarily be protected through the vented chassis containing its functional components. Some critical SPM-H Harsh Environment Starting and Protection Relay hardware elements are its:

• 40 character display
• LED backlighting
• functional programming keys
• RS485 port for serial communication
• Multinet Serial to Ether converter

SPM-H Harsh Environment Starting and Protection Relay I/Os

While the general hardware components critical to this SPM-H Harsh Environment Relay are of course important to consider, so too are the various input and output offerings in its assembly for communication purposes. Some of these include the SPM-H Unit's:

• Field Voltage Input
• Exciter Current Input
• Exciter Voltage Input
• FAR/FCX Relays
• Power Factor Analog Signal Output
• Power Factor Control Signal
• Motor ‘On’ Input and Motor Line Current
