Features:
- 16 digital input channels
- 48 v dc field contacts
- Matched with SDI-1648 safe digital input module
FS-TSDI-1648 provides termination for higher-voltage safe discrete inputs in a Honeywell Safety Manager installation.
Its standard fs construction and the documented 48 V DC field contacts must match the cabinet and field design.
Verify input thresholds, isolation and field supply and the complete connected path before the equipment is released to operation.
The Honeywell FS-TSDI-1648 16-Channel 48 V DC Safe Digital Input FTA is available for quotation and technical support from Apter Power.
