Mini ifB采样装置介绍：
PPM Technology 迷你接口板 (m-ifB) 配有内置的 Formaldemeter 单元，旨在连接到第三方系统。接口板可配置不同电压输出；4-20mA电流输出，同时提供继电器报警输出。有多种操作模式可供选择，以适应各种用途、应用和情况。
有一个配置菜单可供用户选择输出类型、操作模式、选择输出测试、采样范围以及校准 Formaldemeter。该菜单还允许在各种浓度下触发内置的无电压继电器，以便控制外部设备。
Mini 接口板 (ifB) 配有 Formaldemeter htV，并且经过全面校准并可以使用。只需将外部输出连接到 mini ifB 并打开即可。
迷你 ifB 可用于三种采样模式之一：
• 轮询模式
在此模式下，仅当在采样输入线上检测到有效脉冲时才会进行采样。如果此时仪器还没有充分清理以进行采样，那么采样将被延迟——一旦仪器准备好，就会进行采样。这非常适合与 PLC 或其他基于控制器的系统一起使用，因为采样率由输入线路控制，并且当前状态可作为输出线路上的逻辑电平使用。
• 连续模式
该模式不需要任何外部触发进行采样。Formaldemeter 会尽可能频繁地取样。采样持续时间将取决于样品浓度（更高浓度的样品将需要更长的时间来清除并延迟下一个样品）。此模式易于设置，非常适合没有基于控制器的系统可用且采样频率可能变化的应用。
• 定时模式
该模式不需要外部触发，但与之前的连续模式不同，它使用内部定时器以设定频率触发样本。这可以由用户在 1 到 60 分钟之间以一分钟为增量进行调整。但是，不能保证采样频率，因为如果 Formaldmeter 未准备好在指定时间采样，采样可能会延迟。

英文原文：
The PPM Technology mini interface board (m-ifB) comes complete with a built in Formaldemeter unit which is designed to connect to third party systems. The interface board can be configured to give different voltage outputs; a 4–20mA current output and also give a relay alarm output. Various modes of operation are available to suit a whole array of uses, applications and situations.
There is a configuration menu available to allow the user to choose output type, operation mode, select output tests, sampling range and also calibrate the Formaldemeter. The menu also allows for the incorporated voltage-less relay to be triggered at various concentrations so that external equipment can be controlled.
Typical Uses:
Simple integration into exisiting sensor networks
PLC control systems
Stand–alone area monitoring
Cleanrooms; Packing rooms & Workshops
Single-point remote monitoring
The Mini interface board (ifB) comes complete with a Formaldemeter htV, and is fully calibrated and ready to use. Simply connect your external outputs up to the mini ifB and switch on.
The mini ifB can be used in one of three sampling modes, depending on what best suits your needs. These are:
• Polled mode
In this mode samples are only taken when a valid pulse is detected on the sample input line. If the instrument has not cleared sufficiently to sample at this point then the sample will be delayed — as soon as the instrument is ready then a sample will be taken. This is ideal for use with PLC or other controller based systems as the sampling rate is controlled by the input lines and the current status is available as logic levels on the output lines.
• Continuous mode
This mode does not require any external trigger for sampling. Samples are taken as often as possible by the Formaldemeter. The sampling duration would be dependant on sample concentration (higher concentration samples will take longer to clear and will delay the next sample). This mode is easy to setup and is ideal for applications where no controller based systems are available and the sampling frequency can vary.
• Timed mode
This mode does not require an external trigger but unlike the previous continuous mode it uses an internal timer to trigger samples at a set frequency. This can be adjusted by the user between 1 and 60 minutes in increments of a single minute. However, the sampling frequency is not guaranteed as samples may be delayed if the Formaldmeter is not ready to sample at the designated time.
