PW 100

The compact allrounder

The Pw¹⁰⁰ is a transparent level converter for 100 M-Bus slaves with an abundance of interfaces and functions. Whether you read your meters with a DDC, involving them directly in your building control or want to access the data on a PC, the Pw¹⁰⁰ with its RS232C, RS485, USB and TCP / IP interfaces offers all options. Another unique feature related to the large number of interfaces is their intelligent management. By this the Pw¹⁰⁰ allows you to connect multiple external controllers simultaneously. The access to the M-Bus is monitored by a logic, that always connects only one interface at a time. By the additionally implemented repeater function, the Pw¹⁰⁰ becomes the true allrounder among our compact DIN rail M-Bus level converters.

Operation and Features

The Pw¹⁰⁰ is a digital M-Bus level converter for up to 100 M-Bus slaves. The integrated processor takes over the control of the short-circuit protection, the collision detection and the bit time recovery. As one of few level converters for 100 meters the Pw¹⁰⁰ provides communication speeds of up to 38400 baud. Different colored LEDs on the front of the housing inform you about the device status and indicate communication. Another LED shows that one of the available interfaces is in access to the M-Bus. Here, the intelligent controller ensures that either the RS232C or RS485 or USB or TCP / IP interface is switched to the M-Bus. After completing the communication the M-Bus is released and reallocated according to the principle „first come, first served.“. Being installed the Pw¹⁰⁰ trades in all advantages of its compact DIN rail housing and fits perfectly into your switch cabinet. If you are using the Pw¹⁰⁰ as a repeater for an existing M-Bus system, it enables the connection of 100 M-Bus slaves or a extension of the cable network up to 4 km.
