NCE BD20 Block Detector Module REC_SES_103 The transistor outputs of theDetects DCC track current being drawn through a single track feeder. Isolated so there is no direct electrical connection to the track. Needs no external power for most operations. Can be connected to the NCE AIU01 or Mini Panel. Can an light up LED or operate a relay when used with external DC power (5 12 Volts). Suitable for DCC track power up to 20 Amps.
