Milliamp Output Modules
MAI mA Input Interface Module
Accepts a 0-20 mA input signal at 1.5 volts and produces a 0-20 mA at 20 volt signal to drive multiple loads/controllers. MAI can also accept a potentiometer input (135 Ohm thermostat or any 1K pot) and produce 4-20 mA @ 20 V to drive all SCR power controls, valve positioners, etc. The MAI can be modified to accept DC voltage inputs and convert them to a 4-20 mA control signal to drive SCR and TRIAC controls. (D.C. voltage input ranges must be ordered as options, contact us for availability). Operates on 120 VAC, 208-277 VAC, or 480 VAC.
MAP Series Manual Potentiometer 0-20 mA Output Source
Same as MAI but has potentiometer with 2 ft. of wire, 0-100 dial and knob ready for panel mounting. Works to control all "A" series controllers for open loop control. Operates on 120 VAC, 208-277 VAC, or 480 VAC. Will also work with 4-20 mA signal as an amplifier/trim adjustment.
MTP Series Manual Potentiometer Solid State Relay Driver
MTP produces a fast time proportioning 20 VDC signal for driving Solid State Relays (SSRs). MTP has a power output limit adjustment of 63 - 100%. The MTP accepts the same inputs as the MAI (potentiometer, mA, D.C. Voltage, or 135 Ohm thermostat). The MTP is supplied with potentiometer with 2 ft. of wire, 0-100 dial and knob. Can run over 10 SSRs.
For 4-20 mA Input SSR Driver use MITP. MITP mounts onto SSR.
