Cooper Instruments DCM490 Specifications
DCM 490/492 - UNIVERSAL IN-LINE AMPLIFIER
he DCM 490 and DCM 492 are highly serviceable, userprogrammable units that meet NEMA-4 and IP-66 ratings for water
T
resistance. These units are housed in a rugged, plastic package
which is connected between the transducer and the readout device. The
amplifier supplies a regulated bridge excitation voltage for the transducer
and will give an output of 0-5 Vdc (DCM 490) or 4-20mA (DCM 492).

DCM 495/496 - UNIVERSAL IN-LINE AMPLIFIER
he DCM 495 and DCM 496 are highly serviceable, userprogrammable units that meet NEMA-4 and IP-66 ratings for water
T
resistance. These units are housed in a rugged, plastic package
which is connected between the transducer and the readout device. The
amplifier supplies a regulated bridge excitation voltage for the transducer
and will give an output of 0 to +/- 10 Vdc (DCM 495) or 0 to +/- 5 Vdc
(DCM 496).
