OTEK Corporation Current Transformer-Powered Loop Transmitter Model CTT

OTEK's new "CTT" is a variation of the company's recently introduced ACS Series that brought you the World's First Truly C.T. (Current Transformer) powered instruments to monitor or control A.C. variables (V, A, W & Hz). Now OTEK brings you complete freedom and savings. The "CTT" is 100% powered by your on site 5 Amp C.T.. Just connect your C.T. output to the CTT, your current loop load and eliminate the conduit power supply & wires. The convenient plug-in screw terminal connectors (26-16 Ga), allows for quick installation. POWER: The CTT is powered by your C.T. and just like analog meters, if the C.T. is dead or has below minimum current output, the CTT won't display or transmit. For applications requiring display and transmission, even at no input, order CTT externally (24VDC) powered (Digit 3, Option 1). The optional display (Option 3) displays the loop value in bright red 4 1/2 LED digits, 0.25" high. Standard calibration is 4-20mA=0-10000 counts. The optional isolator (Option 1, 3rd digit) give you >2K V isolation between inputs and loop output and requires >7<32 VDC, plus your load burden. PACKAGES: The DIN Rail (Option 1) is only 1" wide x 3.1 H x 3" deep. The Nema 4X (Options 2 & 3) can be wall, panel or pipe (NPT 1/2") mounted. Standard Calibration is 0-0.4A no display, 0.5A = 5.6mA = 625 counts, 5A = 20mA = 10000 counts. Zero and Span pots are included. 4 & 20mA output adjustments are also included. You can mount the CTT next to, or remotely from your 5A C.T. Just consider the wire resistance (0.0040 Ohms/Foot x 2 for 16 Ga.) and the CTT's internal resistance (0.05 Ohm). It works best if you mount the CTT closest to your C.T. Note: The C.T. A inputs are internally fused with a 10A fuse. You should fuse your C.T. output at 8A or less. The V, W & Hz are fused internally with a 2A fuse. Use a 1A fuse externally.
