ES-5221 Rev.9 MODEL Telemetering System TMR/TMT Functions & Features

  • Transmitting 1-point contact signal through NTT (Nippon Telephone & Telegraph) personal telecom- munication line of 50 b/s • Approved of Technical Requirements Compliance Approval by Japan Ap- proval Institute for Telecommunications Equipment
  • Approval No. M90-N227-0 • Applicable to vari- ous cables types • No interference by induction noise
  • Lightning protection applicable • No field adjust- ment required • Compact plug-in construction easy to install and maintain MODEL & SUFFIX CODE SELECTION TM ❑ –❑ MODEL INPUT Dry contact OUTPUT R : Relay contact T : Open collector POWER INPUT AC Power DC Power B : 100V AC G : 200V AC S : 12V DC* C :1 10V AC H : 220V AC R : 24V DC* D :1 15V AC J : 240V AC F : 120V AC *24V DC (Code R) and 12V DC (Code S) are not ap- proved by Japan Approvals Institute for Telecommu- nications Equipment.
