Dwyer Series 16L Limit Controls

FM Approved, Large, Dual Display, Universal Input
STANDARD FEATURES
FM Approved Limit
Large Dual Display
Universal Input
Dedicated, Illuminated Reset Key
Remote Reset Capability Standard
Four Password Protected Security Levels
The 16L Series Temperature/Process FM Approved Limit Controls set a new standard in 1/16 DIN limit controls. Full compatablity with Love’s 16A Series of controls offers family interchangeability with different levels of features. Ease of use is assured with consistant programming and a dedicated front panel reset key that flashes for limit conditions.

The 16L offers universal input (10 thermocouple types, 4 RTD types, voltage, and current), single set point or dual set point. Standard features include Remote Reset capability, Peak/Valley indication, open sensor protection, input rate of change protection, and much more.

Outputs include AC and DC solid state relays, DC SSR drive, and normally open (form A) and normally closed (form B) relays. Form A and form B relays can be setup one for each set point output and logically linked to emulate a form C output. Options for the 16L include Process Output Retransmission (Voltage or Current), RS-485 Serial Communication, and low voltage (12-24 V) operation.

Designed and built in the USA, the 16L family of controls offers the highest levels of features, function, and quality available today. See Dimensions
