TK-IOLL01 HONEYWELL I/O LIM Link Interface Module

The Honeywell TK-IOLI01 is an I/O Link Interface Module (often referred to as “IOLIM” in Honeywell literature) used in industrial control/automation

systems, particularly in conjunction with Honeywell’s Experion / C200 / C300 / Series C / Series 8 platforms. It acts as a communication

gateway/interface between the supervisory controller chassis (e.g., the C200/C300) and the I/O subsystem (PM I/O

modules/field I/O link). In simpler terms, it enables the control system to talk to I/O modules

connected via I/O-Link or proprietary “link” networks.

Q1: What is the main purpose of the TK-IOLI01 module?
A: Its primary role is to interface between the control system (controller chassis) and the I/O link network (PM I/O modules / remote I/O). It enables I/O link communication, supports scalability of I/O modules, and facilitates redundancy.

Q2: Which control systems support the TK-IOLI01?
A: It is used in Honeywell’s Experion / C200 / C300 / Series C / Series 8 I/O architectures (or PM I/O architectures). For example, documentation

refers to I/O Link modules in the Series C I/O specification. 

Q3: Can the module be installed while the system is live / powered?
A: No — installation documentation warns that removal or insertion of an I/O Link Interface module will affect the process.

Proper shutdown procedures should be followed. 

Q4: What redundancy features does the module support?
A: The I/O Link network supports redundant links (Link A and Link B). The IOLIM supports these

redundant links in configurations requiring higher availability. 

Q5: What environment/temperature range is allowed?
A: According to one source: operating temperature –20 °C to +60 °C; storage

 –40 °C to +85 °C; humidity 5%-95% non-condensing.
