Features:
- Honeywell specification names exact 621-2100R.
- Eight 115 VAC isolated outputs are listed.
- The module is assigned IEEE 518 DATA 3 wiring class.
Honeywell's September 1995 Logic Manager specification lists 621-2100R in its digital-output model table as an eight-output 115 VAC isolated module. The table also lists 621-2102R as a different eight-output 115 VAC execution and multiple other AC and DC variants. Therefore the exact model suffix matters. The manufacturer assigns DATA 3 under IEEE 518 for the listed 621-2100R circuit, while noting that signal-level wiring classification depends on the actual voltage and current present in the installation. Use the plant's approved electrical design to interpret that class.
The reviewed manufacturer PDF verifies model, output count, nominal AC class and isolation description, but does not give a complete load-current, fuse or terminal-assembly specification for this individual card. Obtain those from the physical module and applicable installation manual. Before removal, document every output, field-load voltage, fuse, terminal mapping, rack position, addressing and original diagnostic state. Qualified personnel should isolate and verify the AC circuit under current procedures, fit only a verified compatible replacement, then prove each output and its safe response. Do not copy ratings from neighboring Logic Manager modules merely because they share a voltage class.
The 621-2100R Honeywell Logic Manager 115 VAC Isolated Output Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell 621-2100R official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
The Honeywell table identifies 621-2100R as an eight-point 115 VAC isolated digital-output module. That description is exact-model evidence, not an invitation to use another 115 VAC card's specifications. Confirm the physical module and its field-load arrangement, including isolation and fusing, before replacing a working card in a legacy rack.
Honeywell assigns IEEE 518 DATA 3 signal-level wiring classification to this listed module and notes that classification can vary with actual voltage and current. Keep the installed panel wiring, segregation, protective devices and local electrical code in view. The reviewed table does not provide the full terminal map or load-current rating needed for a field installation.
The manufacturer-authored 1995 specification names exact 621-2100R, output type and count. It does not establish the condition or revision of the supplied item, a current support entitlement or detailed load limits. The PDF is mirrored by a third party. Verify rack compatibility, connectors, labeling and each field circuit against the plant's original system drawings and current service procedure.
