16L
Series Limit Control |
The 16L series FM Approved Limit Controls for temperature
/ process applications set a new standard in 1/16 DIN power, flexibility
and value. Completly interchangable with the Dwyer 16A Series, the
16L Series offers a high level of features in a compact size.
Options for the 16L include Process Output Retransmission (Voltage or Current), RS-232 Serial Communication, or RS-485 Serial Communication.. Designed and built in the USA, the 16L family of controls offers the
highest levels of features, function, and quality available today.
