The ISO15M and ISO35M have extended ambient temperature ratings of –55°C to 125°C while the ISO15 and ISO35 are specified over –40°C to 85°C. 1 Meets or Exceeds TIA/EIA RS-485 Requirements 1/8 Unit Load – Up to 256 Nodes on a Bus Signaling Rates up to 1 Mbps Thermal Shutdown Protection Low Bus Capacitance – 16 pF (Typical) 50 kV/μs Typical Transient Immunity Fail-safe Receiver for Bus Open, Short, Idle 3.3-V Inputs are 5-V Tolerant Safety and Regulatory Approvals – 4000-VPK VIOTM, 560-VPK VIORM per DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 and DIN EN 61010-1 – 2500 VRMS Isolation Rating per UL 1577 – 2500 VRMS Isolation Rating per CSA CA5A and IEC 60950-1 2 Applications • • • • • • Security Systems Chemical Production Factory Automation Motor and Motion Control HVAC and Building Automation Networks Networked Security Stations These devices are ideal for long transmission lines because the ground loop is broken to allow for a much larger common-mode voltage range. The symmetrical barrier of the device is tested to provide isolatlion of 4000 VPK per VDE and 2500 VRMS per UL and CSA between the bus-line transceiver and the logic-level interface. Any cabled I/O can be subjected to electrical noise transients from various sources. These noise transients can cause damage to the transceiver and/or nearby sensitive circuitry if they are of sufficient magnitude and duration. These isolated devices can significantly increase protection and reduce the risk of damage to expensive control circuits.
